Main Question or Discussion Point
In my physics text book, temperature is defined as a measure of the average KE of random translational motion of particles. It also states that temperature does not account for the KE from molecular vibration or molecular rotation. In an earlier chapter, my text describes the motion of atoms in solids as vibrational motion - I take it that these atoms do not have translational motion. If this is the case, how is temperature measured for solids? Temperature would be the average KE of what?
